Planned time excludes only time when production was not scheduled. Availability does not measure calendar utilization. Concept diagram; not to scale.

Separate equipment losses into availability, performance and quality, then calculate OEE.

Availability = 100*t/p %
Performance = 100*c*n/(60*t) %
Quality = 100*g/n %
OEE = 100*c*g/(60*p) %

Worked example

  • Planned production time (min): 480
  • Run time (min): 420
  • Ideal cycle time (s/unit): 2
  • Total units produced: 12000
  • Good units without rework: 11400
  • Availability: 87.5 %
  • Performance: 95.24 %
  • Quality: 95 %
  • OEE: 79.17 %

Assumptions and limits

Use one consistent production period and a verified ideal cycle. Good units exclude rework. Performance above 100% is rejected because it signals inconsistent inputs or an unsuitable ideal cycle.

Results are rounded for display; calculations use unrounded values. Read our calculation methodology.

Understanding the result

Separate equipment losses into availability, performance and quality, then calculate OEE. Planned time excludes only time when production was not scheduled. Availability does not measure calendar utilization.

When this tool is useful

Frequently asked questions

What does this model leave out?

Use one consistent production period and a verified ideal cycle. Good units exclude rework. Performance above 100% is rejected because it signals inconsistent inputs or an unsuitable ideal cycle.

How do I reproduce the example?

Enter the displayed example values in their labelled units. Apply the formula before rounding; change one input at a time to compare scenarios.
